While dual wielding, the player adopts a modified ASPD formula and incurs a penalty to their righthand and lefthand weapon ATK. The modified ASPD formula references a new base weapon delay equal to 70% of the culmulative delay for each weapon. The weapon ATK penalty is 50% and 70% for righthand and lefthand weapons respectively, and may be decreased with the Righthand and Lefthand Mastery skills.

atk = atk_r + atk_l atk_r = wpn_atk_r * (0.5 + 0.1 * righthand_mastery_lv) atk_l = wpn_atk_l * (0.3 + 0.1 * lefthand_mastery_lv)

wpn_delay = 0.7 * (wpn_delay_r + wpn_delay_l)

Many mechanics only reference the righthand weapon, i.e. the lefthand weapon attributes (ATK, weapon class) are not referenced in skill calculations and are not modified by physical modifiers, e.g. +% damage or +% status. However, modifiers presented by the lefthand weapon are applied to the righthand weapon. ATK properties, e.g. DEF Ignore or Investigate, apply to both weapons. An example is presented below.

# RH: Gladius [3], 3x Skel Worker Card # LH: MGauche [4], 4x Hydra Card # Righthand Damage dmg = [(105 # Wpn ATK * (0.5 + 0.1 * righthand_mastery_lv)) + atk_f(str, dex, luk) # +ATK [stats] + 3 * 5] # +ATK [cards] * (1 + 0.15 * 3) # Size Modifier * (1 + 0.20 * 4) # Race Modifier # Lefthand Damage dmg = [(43 # Wpn ATK * (0.3 + 0.1 * lefthand_mastery_lv)) + atk_f(str, dex, luk) # +ATK [stats] + 3 * 5] # +ATK [cards]
